New arguments: -l –library targetLib name (new) -s targetLib name -m pcmname (can be many -m) (new) -m pcmname (can be many -m) –rootmap -rmf (new) –rootmap-lib -rml (new)

genreflex options which rise warnings (feedback is desirable) –no_membertypedefs (it should be irrelevant) –no_templatetypedefs (it should be irrelevant)

genreflex options which are ignored (know for sure they are not needed) –pool, –dataonly –interpreteronly –gccxml{path,opt,post}

Exceptions The –deep option of genreflex is passed as function parameter to rootcling since it's not needed at the moment there.
